Meet us at VSS-2024, Florida

The fMRI-at team will be at the Vision Science Society conference in Florida from May 17th to 22nd, talking about our latest research on retinotopy. We’re excited to meet other researchers and chat about our work. Come join us for some interesting discussions about how our brains make sense of the world around us! See you there!

Optimal preprocessing pipeline for fALFF

Leave a reply

Resting‐state functional magnetic resonance imaging (rs‐fMRI) offers the possibility to assess brain function during rest. This absence of explicit stimuli in fMRI makes analyses more susceptible to noise than task‐based fMRI.

Data preprocessing is a critical procedure to minimise artefacts related to motion and physiology.

A paper recently published in Human Brain Mapping evaluates the effects of different preprocessing strategies on the amplitude of low‐frequency fluctuations (ALFFs) and fractional ALFF (fALFF). We give important recommendations and identified preprocessing strategies that have a negative impact.
